Reduces the amount of feedback from your acoustic guitar without any loss of tone.

The Dunlop Suppressor Pro reduces the amount of feedback from your acoustic guitar without any loss of tone. Developed by innovative guitar builder Todd A. Falk, the louver design lets air flow through the soundhole-allowing the top to vibrate naturally-so your true acoustic tone rings through. This essential stage tool is made of a light weight aluminum plate and soft rubber ring that will fit most standard acoustic guitars. Turn your volume up on stage without the fear of feedback with the Dunlop Suppressor Pro.

The Screeching Halt is lighter and more flexible since it is entirely made of rubber. I ended up putting a strip of light adhesive felt around the perimeter of both because my guitar's sound hole is about 1/8" wider than the 4" these were designed for. Since the Screeching Halt is flexible, putting it in and taking it out is a bit easier. I recommend the Screeching Halt. The Suppressor and the Screeching Halt both mute the acoustic tone of my dreadnought about the same and both make it bullet proof to feedback at high volumes. Both are made well.I don't find the Suppressor Pro more attractive or different in performance compared to the cheaper Screeching Halt.
